Contour Enthusiasts Group Archives Forums General Dyno and Drag Anyone do a dyno with a stock Zetec?

I'd like to know about the exhaust too. I'm wondering what the extreme decrease in back pressure did for the actual performance numbers.

It seems to add quite a bit. But that may just be me.

I wonder how you figure the actual % for your specific car? You'd almost have to know the hp at the wheels and at the crank...as seperate measures.

Using the 110 figure above it would be about 15% roughly.

Guys, look at the CTA dynos by Chris Wong linked on this forum. ZX2 and ZX3 Zetec dynos. Stock about 103 FWHP, with KKM 106 FWHP, with CTA intake + ignition 109 FWHP or so I think. Torque 112 - 118 or so, pretty decent.

well my 104 number wasn't to far off then.
